Eagle is the common name for the golden eagle, bald eagle, and other birds of prey in the family of the Accipitridae. Eagles belong to several groups of genera, some of which are closely related. True eagles comprise the genus Aquila. Most of the 68 species of eagles are from Eurasia and Africa. [1]
[8] [12] The Afrikaans name for the tawny eagle is a "Roofarend", meaning the "Robber Eagle". [8] This behaviour is not entirely segregated from their scavenging on carrion behaviours but the considerable aggressiveness and boldness of the eagles in this circumstances are very different from their rather retiring disposition in scavenging contexts.
Booted eagles are eagles that have fully feathered tarsi. That is, their legs are covered with feathers down to the feet. Most other accipitrids have bare lower legs, scaled rather than feathered. They may be treated as an informal group, as distinct from "fish eagles" (or "sea eagles"), "snake eagles", and "giant forest eagles".
Golden eagles may express their aggression via body language while perched, typically the adult female when confronted by an intruding eagle: the head and body are upright, feathers on head and neck are erect; the wings may be slightly spread and beak open; often accompanied by intense gaze.
The long-crested eagle (Lophaetus occipitalis) is an African bird of prey characterised by its shaggy crest of feathers. In the family Accipitridae which includes all the eagles, it is currently placed in a monotypic genus Lophaetus. It is found throughout mid- and southern Africa, with differing home ranges due to food availability and ...
The subadult eastern imperial eagle may be confused with older immature greater spotted eagles (Clanga clanga) but the latter is less contrastingly patterned, without a paler shawl and has greater covert band below (despite the rare hint of one on some imperials) and densely bared flight feathers. Adult greater spotted eagles have similar ...
Wedge-tailed eagles are typically creamy white on the cere and feet, although those can be dull yellow, more so in juveniles than adults. [4] The wedge-tailed eagle has a unique moult process in that they moult almost continuously and very slowly, and it might take three or more years for an eagle of the species to complete a moult.
